What is non-sustained ventricular tachycardia?

Tachycardia is a term used to describe an unusually fast heartbeat caused by an irregular electrical pulse in the ventricle. When it occurs in the lower chambers of the heart (ventricles), it is called ventricular tachycardia. A ventricular tachycardia that stops alone for 30 seconds is called a nonpersistent ventricular tachycardia. Any ventricular tachycardia is considered at least a dangerous arrhythmia. Since non-sustained tachycardia does not persist, it is less dangerous than persistent ventricular tachycardia (SVT), and the result can be entirely benign. However, it can still cause potentially worrisome symptoms and may indicate an increased heart risk.

Symptoms.

The formal definition of short array ventricular tachycardia is heart rate of at least 120 beats per minute, lasting at least 3 times, lasting no more than 30 seconds. In most cases, it doesn't cause any symptoms at all, or just heart palpitations. Because this tachycardia usually does not produce worrisome symptoms, it is often found by accident during recording an electrocardiogram (ECG) or other heart monitoring.

Causes.

  • Previously unknown underlying heart disease
  • An arrhythmia caused by the instability of the heart's electrical waves, similar to ventricular fibrillation.

Treatment.

In most cases, a major indicator of the treatment of NSVT is the presence of underlying heart disease. If heart disease is found, treatment should be directed at this point. If it is not and NSVT is not serious, there is no need for treatment from a strict medical point of view. Keywords: non sustained ventricular tachycardia; nonsustained ventricular tachycardia
